Looking good.

Yes, stock so far. The Vortex generator added major detail/looks for some particular reason. I love it.
I would check your local Subaru dealer for it. Mine came as an option during purchase of the car. I'm sure there are many aftermarket ones available via online.

The 1 Million Mile warranty. lol, jk, Honestly it is a better quality then the stock filter. IMO

Nice photos. What gives you the impression it's better than stock? The stock filter is far better at filtering the air than the K&N for a couple of reasons. First of all, it has smaller holes and thus filters smaller particle sizes. Secondly, oiled filters are designed to work better and better as they get dirtier because this reduces the hole sizes, thus filtering smaller particles. However, even once the filter becomes dirty, it still won't filter as small particles as the stock filter. This means your K&N filter is letting much dirtier air into your engine than the stock filter for at least the first few thousand miles, and will always not filter as well as the stock filter. Last thing, the stock air intake system, including the filter, already flows more air than the stock engine can use with the stock tune.

Well I've taken few things into factor here, first of all I wont argue that the stock filter, filters more dirtier air particles than over the K&N, but I dont really live anywhere where its extremely dusty nor windy all the time where there is a higher potential for my WRX's motor too be damaged, plus I'm not running my WRX off dirt roads doing a little rally fun or anything of that nature, so in those scenarios your opinion would make sense. Ive replaced all of my vehicles with a K&N replacement filter, all between perhaps the 15,000-40,000 mile marker, that includes my BMW Z3 Coupe and Scion TC, (N/A vehicles) and my daily driven vehicle the Scion TC with 159,000+ miles, has given me absolutely no problems what so ever.
I keep all my vehicles very well maintained. I'd have to say though, every time I've switched the stock air filter with a K&N, I've always noticed a significant increase in throttle response/better freeway pick-up, and although its not much its still a difference that I've felt over time, and still no problems, and aren't anticipating any regarding the K&N filters high reputation in regards to daily driving and race cars.
I'm aware that the WRX is different than my other vehicles due to being turbocharged. My cousin actually used to own a Mitsubishi EVO 9 MR and I remember his theory of not wanting to upgrade the motor and he just wanted too make his car lighter. He never did any motor upgrades, but he did replace his air filter from stock to K&N when he first purchased. He put more than 50,000+ miles on his EVO and never did I hear him complain about any motor problems, or any horsepower loss. He too was good at maintaining his EVO.
Thanks for the love and input though
